Mercury 2 is now available on Azure Foundry.
The world's fastest reasoning language model, built to make production AI feel instant.
Mercury 2 doesn't decode sequentially. It generates responses through parallel refinement, producing multiple tokens simultaneously and converging over a small number of steps.
Over 1,000 tokens per second on widely-deployed NVIDIA GPUs, at less than half the cost, with comparable quality to Claude Haiku 4.5 and GPT-5 Mini.
Full announcement:
token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
LLM — A large language model — the neural network behind tools like Claude and ChatGPT, trained on huge amounts of text to predict what comes next.
